The words you use can disclose identifying features. This tool attempts to determine an author’s gender based on the words used. Submitted text is evaluated based on two types of writing: formal and informal. Formal writing includes fiction and non-fiction stories, articles, and news reports. Informal writing includes blog and chat-room text. (Email can be formal, informal, or some combination.) You should view the results based on the appropriate type of writing.
Here’s the screenshot for male writing result :
A few quick notes:
- The system generates a simple estimate (profiling). While Gender Guesser may be 60% – 70% accurate, it is not 100% accurate. This is better than random guessing (50%), but should not be interpreted as “fact”. In particular, men should not be offended if it says you write like a girl.
- People write differently in different forums. For example, a single writing sample may appear MALE for informal writing but test as FEMALE for formal writing. Be sure to interpret the results based on the appropriate writing style. (These notes, for example, are more informal/blog than formal/non-fiction.)
- Many factors can impact the interpretation from any single person’s writing. The content, knowledge of the material, age of the author, nationality, experience, occupation, and education level can all impact writing styles. For example, a woman who has spent 20 years working in a male-dominated field may write like her co-workers. Similarly, professional female writers (and experienced hobbyists) frequently use male writing styles. Gender Guesser does not take any of these factors into account.
- Email can blur the lines between formal and informal writing styles. An informal email from a manager may have traces of formality, and a formal email from a 12-year-old is likely to be informal compared to a letter from a 40-year-old. Do not be surprised if email messages sent to public forums test incorrectly — when writing for an audience, people commonly use informal words, phrases, and slang within a formal writing style.
- Quotations, block quotes, and included text usually carries the gender from the initial author. Be sure to remove quoted text from any pasted content. Also, significant changes from a copy-editor can result in a different gender analysis. (A male editor may make a female author’s news article appear MALE or as a Weak MALE.)
- Lyrics, lists, poems, and prose are special writing styles. This tool is unlikely to classify these texts correctly.
- The system needs a paragraph or two of text in order to observe word repetition. A good sample should have 300 words or more. Fewer words can lead to more variation in accuracy, and a single sentence is unlikely to generate an accurate result. Pasting the same text multiple times will not change the results!
- People tend to write with consistent styles. If the system misclassifies a particular author, then other writings by the same author will likely be misclassify the same way.

A Japanese researchers team has developed a reagent that can make cancer cells glow and become visible to the naked eye, an advance that could help surgeons more accurately distinguish between cancerous and healthy tissue, the medical journal Science Translational Medicine reported Wednesday.
Chemical reagent that makes the cells glow in a rat’s stomach filled with ovarium cancer cells.
Within minutes, the sprayed reagent, developed by Yasuteru Urano, a chemical biology professor at the University of Tokyo, and Hisataka Kobayashi, chief scientist at the U.S. National Institutes of Health, can highlight carcinoma smaller than 1 mm, which magnetic resonance imaging and other tools cannot detect. The team’s attention was drawn to an enzyme on the cell surface that works like scissors to cut off glutamic acid from glutathione, and the researchers created a molecule that glows green only when the glutamic acid is cut off.

The Japanese team succeeded in making cancer cells glow more than 20 times brighter than regular cells by spraying the reagent on the abdomen of mice. Their abdomens had been implanted with human ovarian cancer cells, the team said. The team is still testing to see whether the fluorescent molecule could be poisonous to cells, but they said no hazardous effects have been detected so far even by using large amounts of the reagent. They aim to put the reagent to practical use within a few years as an easy and low-cost tool at hospitals to find cancers and remove them without overlooking small carcinoma. Cancer is the largest cause of death among Japanese, followed by heart failure and cerebral vessel disease.
If you haven’t been to a mall recently, you may not be aware that remote control helicopters are the hot new item for 2011. They are showing up everywhere these days, and there is good reason for it. The technology that they use has finally graduated to the mainstream.
Let’s take a quick look at whats available out there and what the differences are between a $25 helicopter and a $200 helicopter.
Micro Helicopters are the least expensive of the bunch. They are remote controlled via infra red and are very forgiving for any new pilot. They are of the co-axial style, which means that they have two counter rotating main rotor assemblies to make them very stable in flight. The micro heli is also very forgiving with crashes and what are called blade strikes. (when the blade hits something that won’t give) If you are buying for an 8 or 10 year old, this is the way to go. The micros usually recharge through a cable from the controller to the unit and can be flown indoors without too much worry for damage to anyone or anything.

They said it could be done and now they’ve done it. What’s more, they did it with a GRIN. A team of scientists with the U.S. Department of Energy (DOE)’s Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California, Berkeley, have carried out the first experimental demonstration of GRIN – for gradient index – plasmonics, a hybrid technology that opens the door to a wide range of exotic optics, including superfast computers based on light rather than electronic signals, ultra-powerful optical microscopes able to resolve DNA molecules with visible light, and “invisibility” carpet-cloaking devices.
Working with composites featuring a dielectric (non-conducting) material on a metal substrate, and “grey-scale” electron beam lithography, a standard method in the computer chip industry for patterning 3-D surface topographies, the scientists have fabricated highly efficient plasmonic versions of Luneburg and Eaton lenses. A Luneburg lens focuses light from all directions equally well, and an Eaton lens bends light 90 degrees from all incoming directions.
“This past year, we used computer simulations to demonstrate that with only moderate modifications of an isotropic dielectric material in a dielectric-metal composite, it would be possible to achieve practical transformation optics results,” says Xiang Zhang, who led this research. “Our GRIN plasmonics technique provides a practical way for routing light at very small scales and producing efficient functional plasmonic devices”.
Zhang, a principal investigator with Berkeley Lab’s Materials Sciences Division and director of UC Berkeley’s Nano-scale Science and Engineering Center (SINAM), is the corresponding author of a paper in the journal Nature Nanotechnology, describing this work titled, “Plasmonic Luneburg and Eaton Lenses.” Co-authoring the paper were Thomas Zentgraf, Yongmin Liu, Maiken Mikkelsen and Jason Valentine.
GRIN plasmonics combines methodologies from transformation optics and plasmonics, two rising new fields of science that could revolutionize what we are able to do with light. In transformation optics, the physical space through which light travels is warped to control the light’s trajectory, similar to the way in which outer space is warped by a massive object under Einstein’s relativity theory. In plasmonics, light is confined in dimensions smaller than the wavelength of photons in free space, making it possible to match the different length-scales linked to photonics and electronics in a single nanoscale device.
“Applying transformation optics to plasmonics allows for precise control of strongly confined light waves in the context of two-dimensional optics,” Zhang says. “Our technique is analogous to the well-known GRIN optics technique, whereas prior plasmonic techniques were realized by discrete structuring of the metal surface in a metal-dielectric composite”.
Like all plasmonic technologies, GRIN plasmonics starts with an electronic surface wave that rolls through the conduction electrons on a metal. Just as the energy in a wave of light is carried in a quantized particle-like unit called a photon, so, too, is plasmonic energy carried in a quasi-particle called a plasmon. Plasmons will interact with photons at the interface of a metal and dielectric to form yet another quasi-particle, a surface plasmon polariton (SPP).
The Luneburg and Eaton lenses fabricated by Zhang and his co-authors interacted with SPPs rather than photons. To make these lenses, the scientists worked with a thin dielectric film (a thermplastic called PMMA) on top of a gold surface. When applying grey-scale electron beam lithography, the scientists exposed the dielectric film to an electron beam that was varied in dosage (charge per unit area) as it moved across the film’s surface. This resulted in highly controlled differences in film thickness across the length of the dielectric that altered the local propagation of SPPs. In turn, the “mode index,” which determines how fast the SPPs will propagate, is altered so that the direction of the SPPs can be influenced.
“By adiabatically tailoring the topology of the dielectric layer adjacent to the metal surface, we’re able to continuously modify the mode index of SPPs,” says Zentgraf. “As a result, we can manipulate the flow of SPPs with a greater degree of freedom in the context of two-dimensional optics”.
Says Liu, “The practicality of working only with the purely dielectric material to transform SPPs is a big selling point for GRIN plasmonics. Controlling the physical properties of metals on the nanometer length-scale, which is the penetration depth of electromagnetic waves linked to SPPs extending below the metal surfaces, is beyond the reach of existing nanofabrication techniques”.
Adds Zentgraf, “Our approach has the potential to achieve low-loss functional plasmonic elements with a standard fabrication technology that is fully compatible with active plasmonics”.
In the Nature Nanotechnology paper, the scientists say that inefficiencies in plasmonic devices due to SPPs lost through scattering could be reduced even further by incorporating various SPP gain materials, such as fluorescent dye molecules, directly into the dielectric. This, they say, would lead to an increased propagation distance that is highly desired for optical and plasmonic devices. It should also enable the realization of two-dimensional plasmonic elements beyond the Luneburg and Eaton lenses.
Says Mikkelsen, “GRIN plasmonics can be immediately applied to the design and production of various plasmonic elements, such as waveguides and beam splitters, to improve the performance of integrated plasmonics. Currently we are working on more complex, transformational plasmonic devices, such as plasmonic collimators, single plasmonic elements with multiple functions, and plasmonic lenses with enhanced performance”.
